Clean the data → Develop a predictive model → Import data → Integrate the model
None of the mentioned above
Correct Answer :
A. Import data → Clean the data → Develop a predictive model → Integrate the model
Before to do predictive analytics, we should follow some sequence. This is like Import data from varied sources, such as web archives, databases, and spreadsheets, Clean the data by removing outliers and combining data sources, develop an accurate predictive model based on the aggregated data using statistics, curve fitting tools, or machine learning and integrate the model into a load forecasting system.
